The technology advances required to meet the 2050 goals are challenging and not assured. Nevertheless, the committee considers that dramatic cost reduction and overall performance enhancement is possible without unpredictable technology breakthroughs. Achieving these goals requires that the improved technology focus on reducing fuel use rather than adding greater power or weight, the report says.
It is impossible to know which technologies will ultimately succeed, the report says, because all involve uncertainty. The best approach, therefore, is to promote a portfolio of vehicle and fuel research and development, supported by both government and industry, designed to solve the critical challenges in each major candidate technology. Such primary research efforts need continuing evaluation of progress against performance goals to determine which technologies, fuels, designs, and production methods are emerging as the most promising and cost-effective.
Overcoming the barriers to advanced vehicles and fuels will require a rigorous policy framework that is more stringent than the proposed fuel economy standards for 2025. This policy intervention could include high and increasing fuel economy standards, R&D support, subsidies, and public information programs aimed at improving consumers' familiarity with the new fuels and powertrains. Because of the high level of uncertainty in the pace and scale of technology advances, this framework should be modified as technologies develop and as conditions change.
It is essential that policies promoting particular technologies to the public are not introduced before these new fuels and vehicle technologies are close to market readiness, and consumer behavior toward them is well understood. The report warns that forcing a te
